What's flexibility worth The enticing case of natural gas cofiring

摘要: The purpose of this article is to show how decision trees can be used calculate the flexibility a utility plan, and demonstrate method by quantifying benefits cofiring natural gas. Cofiring burning gas in primary combustion zone continuously or seasonally, as partial replacement for coal. authors summarize cofiring. There they point out that previous analyses, ignoring uncertainty, could not evaluate cofiring's may therefore have understated its attractiveness. They then present simple example illustrates quantified using trees. close summarizing study which estimate midwestern utility. conclude gives system significantly more than flue desulfurization, buying allowances, switching low-sulfur
